Access the Boot Loader Program
The Boot Loader program can be accessed during the boot process. The
main function of the program is to provide a backup means for restoring the
firmware if the Digi Passport unit will no longer boot. It also provides a
hardware testing module that detects and tests hardware components on
the unit.
To access the Boot Loader program:
1. Connect the Ethernet cable from the console port on the rear panel of
the Digi Passport unit to a serial port on a workstation. Use the Ethernet
cable packaged with the Digi Passport unit and attach the DB-9
adapter. In the photo of the back panel of the Digi Passport unit below,
the arrow points to the console port. (The photo shows the back panel
of a Digi Passport 32.)
2. Set up a terminal emulation program, such as HyperTerminal, using the
following port parameters:
• bps=9600
• data bits=8
• parity=none
• stop bits=1
• flow control=none
3. Turn on the power to the Digi Passport unit.
4. Press ESC within 3 seconds of booting the unit to get Boot Loader
menu.
